Abstract

The Ka band tracking capability of the Cassini spacecraft allows for greater accuracy in most Radio Science experiments, but can be used only with the Goldstone DSN complex, i.e. for one third of the total time. A digital receiver has been designed to allow receiving the Ka band signal from a generic VLBI antenna. The receiver interfaces with the VLBI receiver and formatter. It records an instantaneous bandwidth from 1 Hz to 125 kHz, with corresponding accuracy of 16 to 8 bits respectively. The receiver is implemented as a VME card and is controlled by a standard VME computer.

卡西尼号无线电科学实验用多普勒接收机

卡西尼号航天器的Ka波段跟踪能力可以在大多数无线电科学实验中提供更高的精度，但只能用于Goldstone DSN复合物，即总时间的三分之一。设计了一种数字接收机，用于接收来自通用VLBI天线的Ka波段信号。接收器与VLBI接收器和格式化器接口。它记录从1hz到125khz的瞬时带宽，相应的精度分别为16到8位。接收机被实现为VME卡，由标准的VME计算机控制。

期刊介绍： Planetary and Space Science publishes original articles as well as short communications (letters). Ground-based and space-borne instrumentation and laboratory simulation of solar system processes are included. The following fields of planetary and solar system research are covered: • Celestial mechanics, including dynamical evolution of the solar system, gravitational captures and resonances, relativistic effects, tracking and dynamics • Cosmochemistry and origin, including all aspects of the formation and initial physical and chemical evolution of the solar system • Terrestrial planets and satellites, including the physics of the interiors, geology and morphology of the surfaces, tectonics, mineralogy and dating • Outer planets and satellites, including formation and evolution, remote sensing at all wavelengths and in situ measurements • Planetary atmospheres, including formation and evolution, circulation and meteorology, boundary layers, remote sensing and laboratory simulation • Planetary magnetospheres and ionospheres, including origin of magnetic fields, magnetospheric plasma and radiation belts, and their interaction with the sun, the solar wind and satellites • Small bodies, dust and rings, including asteroids, comets and zodiacal light and their interaction with the solar radiation and the solar wind • Exobiology, including origin of life, detection of planetary ecosystems and pre-biological phenomena in the solar system and laboratory simulations • Extrasolar systems, including the detection and/or the detectability of exoplanets and planetary systems, their formation and evolution, the physical and chemical properties of the exoplanets • History of planetary and space research
